Final answer:
d. contouring. Applying darker tones to the sides of the nose to make it look thinner is an example of contouring, a makeup technique used to sculpt and define the face.
Step-by-step explanation:
Applying darker tones to the sides of the nose to make it look thinner is an example of contouring. Contouring is a technique used in makeup artistry to sculpt and define the shape of the face. By using dark shades to create shadows, and light shades to highlight certain areas, contouring can alter the appearance of facial features.
To make the nose appear thinner, you would apply a darker shade of makeup along the sides of the nose, blending it well to create a natural-looking effect. This technique creates an illusion of shadows, making the nose appear narrower.
Highlighting refers to the application of light shades to emphasize certain areas, such as the high points of the face. Tabbing and blending are not specific makeup techniques and are unrelated to nose contouring.
